I'm looking for any further information anyone can supply about a Mig-21FL in Indian service painted with large blue circles all over the topsides. I'm wondering if there were more than one painted this way, and whether it was camouflage or some sort of recognition marking. Also, the one photo I've found online makes it appear that the plane might have been painted aluminum (except certain areas like the rudder) as opposed to bare metal. Any help appreciated.
